Item 1. Description of Proposed Transaction.

         1.1.  Background.  New Century  Energies,  Inc. ("NCE") is a registered
holding company under the Public Utility Holding Company Act of 1935, as amended
(the  "Act").  Public  Service  Company of  Colorado  ("PSCo"),  a  wholly-owned
public-utility  subsidiary  of NCE,  provides  electric  and retail  natural gas
service primarily in the Denver and Front Range metropolitan areas. Through PSCo
and certain existing  non-utility  subsidiaries,  NCE also engages in activities
related to the supply, transportation and storage of natural gas in Colorado and
Wyoming,  including the  provision of  transportation  services to  nonassociate
utilities.1 NC Enterprises,  Inc.  ("Enterprises"),  a wholly-owned  non-utility
subsidiary  of NCE,  serves as an  intermediate  holding  company for certain of
NCE's non-utility subsidiaries and investments.2

         NCE, PSCo and  Enterprises  are now seeking  authorization  for various
transactions,  as  described  below,  relating  to  the  joint  development  and
ownership by PSCo and  Enterprises  and certain  nonassociated  companies of gas
transportation and related facilities. In furtherance of such joint undertaking,
PSCo and Enterprises  have agreed with Colorado  Interstate Gas Company ("CIG"),
Wyoming  Interstate  Company ("WIC") and CIG Resources Company ("CIGR"),  all of
which  are  direct or  indirect  subsidiaries  of The  Coastal  Corporation,  to
undertake the following transactions: (1) Enterprises and CIG Gas Supply Company
("CIGGS")  will form and acquire  the equity  securities  of and  provide  other
funding to WYCO Development LLC ("WYCO"),  a non-utility  company formed for the
purpose  of  facilitating  the  transactions  described  herein;3  (2) PSCo will
construct the Front Range  Pipeline (as described in item 1.3.1,  below) and WIC
will  construct the Powder River Lateral  Expansion (as described in item 1.3.2,
below) (collectively,  the "Facilities");  (3) WYCO will purchase the Facilities
from PSCo and WIC upon completion of  construction;  and (4) WYCO will lease the
Front Range Pipeline back to PSCo and the Powder River Lateral Expansion back to
WIC under separate but substantially identical long-term lease agreements.

         1.2  Acquisition  of Equity  Securities of WYCO.  Enterprises  requests
authority to acquire the equity securities of WYCO, a Colorado limited liability
company formed by Enterprises and CIGGS to facilitate the transactions described
herein. The membership interests
- --------


         1   See New Century Energies,  Inc.,  Holding Co. Act Release No. 26748
(Aug.1, 1997), 65 SEC Docket at 278. West Gas InterState, Inc. ("WGI"), a 
non-utility gas  pipeline  subsidiary  of NCE, transports gas from the PSCo gas
system to Cheyenne Light, Fuel and Power Company, an associate company. e prime,
inc. ("e prime"), also a non-utility subsidiary of NCE, holds investments in
pipeline and underground gas storage businesses.

         2   Id. at 282.
         3   As described in greater detail in item 1.3,  the  Facilities  to be
acquired and owned by WYCO will consist of interstate and intrastate  pipelines,
compressors  and  associated  equipment  that  will be  used by PSCo  and WIC to
transport gas to their  respective  markets and not to distribute gas at retail.
Accordingly,  WYCO will not be a  "gas-utility  company"  within the  meaning of
Section 2(a)(4) of the Act.

                                        2

<PAGE>



in WYCO  will be  owned  50% by  Enterprises  and 50% by  CIGGS.  The  Operating
Agreement governing WYCO shall be in substantially the form of Exhibit A hereto.
Under the  Operating  Agreement,  Enterprises  and CIGGS will have equal  voting
rights with  respect to the  management  of the  business of WYCO and will share
equally  in all costs and  revenues  of WYCO,  except as  specifically  provided
herein. WYCO shall be managed by a management committee ("Management Committee")
that  will   initially   consist  of  one   representative   and  one  alternate
representative  of each of the members.  Decisions of the  Management  Committee
shall be made by the unanimous vote of the representatives of the members,  with
certain exceptions.

         Enterprises'  total  investment  in WYCO is estimated not to exceed $26
million.  Such investment  would be in the form of Enterprises'  initial capital
contribution to WYCO and subsequent cash  contributions,  open account advances,
or loans,  or any  combination  thereof,  to WYCO.  At present,  NCE proposes to
provide  Enterprises  with the  funds  needed  by  Enterprises  to  fulfill  its
obligations under the Operating Agreement.  NCE will derive the funds needed for
such purpose  from  securities  issuances  (including  issuances of  guarantees)
authorized in separate proceedings4 and from other internally-generated  sources
of cash.5

         1.3  Description of  Facilities.  PSCo and WIC have agreed to construct
the Facilities, which are generally described as follows:

                  1.3.1 Front Range Pipeline.  PSCo shall undertake construction
of approximately  53-miles of 24-inch  diameter  natural gas pipeline  extending
from an  interconnection  with PSCo's Chalk Bluffs  measurement  and compression
facilities,  located just south of the  Colorado-Wyoming  border near  Rockport,
Colorado,  to an interconnection  with PSCo's existing 24-inch pipeline adjacent
to  PSCo's  Fort  St.  Vrain  gas-fired  electric   generating   station,   near
Platteville,  Colorado (the "Front Range  Pipeline").  The Front Range  Pipeline
will be designed initially to create additional transportation capacity from the
Rockport/Chalk   Bluffs   interconnection  to  the  Platteville/Fort  St.  Vrain
interconnection  of approximately  269,000 dekatherms (Dth) per day. CIG and WIC
shall cause the  construction  of all necessary taps and metering  facilities on
their respective pipeline systems and new CIG and WIC interconnections with PSCo
at Rockport to accommodate the full initial design capacity from either WIC's or
CIG's  pipeline  system.  CIG and WIC shall be  responsible  for the  design and
capital costs associated with these related facilities.  In order to support and
maintain the initial  design  capacity of 269,000 Dth per day on the Front Range
Pipeline,  CIG,  WIC and PSCo  shall  enter  into a  facilities  interconnection
agreement  wherein WIC and CIG shall agree to provide  pressures  sufficient  to
effect delivery into the Front Range Pipeline. PSCo shall cause the construction
of all necessary  facilities  on PSCo's  pipeline  system  upstream of the Front
Range Pipeline to
- --------
         4   In this connection, the Commission has authorized the NCE system to
undertake various financings in File No. 70-9007.
         5   Alternatively, as discussed below, WYCO may seek to project finance
the cost of the  facilities  on an initial or refinance  basis.  Such  financing
would be done on a basis consistent with Rule 52(b).

                                        3

<PAGE>


accommodate  the initial  design  capacity.  The estimated cost to construct the
Front Range Pipeline is approximately $25 million.

           PSCo has filed an  application  with the  Colorado  Public  Utilities
Commission ("CPUC") requesting a certificate of public convenience and necessity
to  construct  the Front Range  Pipeline,  as well as  approval  for the related
financing transactions that are described below. (See Exhibit D hereto). PSCo is
seeking  authority  from the CPUC to  commence  construction  of the Front Range
Pipeline by May 23,  1998,6 so that it may complete  construction  and place the
Front Range  Pipeline in service by November 1, 1998,  in time for the 1998-1999
winter heating  season.  As stated in PSCo's  application to the CPUC, the Front
Range  Pipeline is  necessary  for  operational  reasons to  alleviate  capacity
constraints  on its northern  Front Range system.  The Front Range Pipeline will
enable  PSCo  to  expand  its   delivery   capacity   and  provide  it  and  its
transportation  customers  with  access to  several  interstate  pipelines  that
intersect at the Chalk Bluffs "hub,"7 which,  in turn, will provide PSCo and its
customers with much improved access to upstream gas supplies in production areas
and supply basins in the Rocky Mountain Region. Such improved access to upstream
gas supplies should lead to lower priced  supplies of gas becoming  available to
the Front Range market.

                  1.3.2  Powder  River  Lateral  Expansion.  WIC has  agreed  to
install and construct equipment and facilities designed to provide approximately
7400  nameplate  horsepower  of  compression  to be  located  near  Laramie  and
Cheyenne,  Wyoming  ("Phase I"),  for the purpose of expanding  the WIC capacity
into Powder  River and  expanding  that portion of its  existing  capacity  from
Laramie  to  Cheyenne,  Wyoming.   Subsequently,   depending  on  future  market
conditions,  WIC may install and construct  equipment and facilities designed to
supply  approximately  4700  nameplate  horsepower of additional  compression at
Laramie and  approximately  100 miles of 16-inch  pipeline that would loop CIG's
existing  Powder River Lateral  terminating  at the Laramie  compressor  station
("Phase II"), for the purpose of further expanding such WIC capacity  (together,
the Phase I and Phase II expansions are referred to as the "Powder River Lateral
Expansion"). The planned in-service date of the Phase I expansion is November 1,
1998, and,  depending on market conditions,  the anticipated  in-service date of
the Phase II expansion is October 1, 1999.

- --------
         6    Under the current  procedural  schedule in the CPUC  proceeding,
the CPUC should issue its decision on PSCo's application by June 1, 1998.
         7    Hubs are formed at locations where several interstate pipelines
meet, or intersect, and function as the physical transfer  points  between  the
intersecting pipelines where shippers (i.e., buyers and sellers) and traders can
buy,  sell,  exchange  or trade gas or pipeline  capacity  or other  "unbundled"
services  (e.g.,  temporary  storage or parking or loaning of gas). At the Chalk
Bluffs hub,  PSCo would have access to  transportation  (and thus  upstream  gas
supplies) on the CIG and WIC pipelines, as well as on the pipeline facilities of
Williams Natural Gas Company,  Trailblazer  Pipeline Company,  KN Interstate Gas
Transmission Company and WestGas InterState, Inc.

                                        4

<PAGE>


         Phase I of the Powder  River  Lateral  Expansion  will be  designed  to
create additional  transportation  capacity on the WIC pipeline system of 49,000
Dth per day and, subject to future market conditions, Phase II would be designed
to create  additional  transportation  capacity  on the WIC  pipeline  system of
120,000  Dth per day between the point of  interconnection  of the Powder  River
Lateral  with  the  pipeline  system  of  MIGC,  Inc.,  an  interstate  pipeline
subsidiary of Western Gas Resources,  Inc., and the terminus of the WIC pipeline
at the Chalk Bluffs hub. These  facilities will provide PSCo and other customers
of WIC with access to additional  transportation  capacity into the Chalk Bluffs
hub, which, in turn, will provide improved access to upstream gas supplies.  The
estimated cost to construct Phase I of the Powder River Lateral Expansion is $16
million  and the  estimated  cost to  construct  Phase  II,  based on  currently
anticipated facilities, would be $28 million.

         1.4  Sale  of  the   Facilities  to  WYCO.   Upon  the   completion  of
construction,  PSCo  proposes  to sell the Front  Range  Pipeline to WYCO for an
amount equal to the actual  total cost  incurred by PSCo,  as  accounted  for in
accordance with the "Gas Plant  Instructions" of the Uniform System of Accounts,
18 C.F.R.  Part  201,  plus an  allowance  for funds  used  during  construction
("AFUDC")  that is based on a  capitalized  cost of money equal to the lesser of
PSCo's applicable AFUDC rate or the CPUC-authorized  rate of return on rate base
during the period of time when the facilities are under  construction  and prior
to the time when placed in service.

         Likewise,  upon  completion  of  construction  of Phase I of the Powder
River Lateral Expansion, WIC will sell a 100% interest in the Phase I facilities
to WYCO, and, if market conditions  justify  construction of the Phase II of the
Powder River Lateral  Expansion,  WIC will sell an  approximately  32% undivided
interest in the  completed  Phase II  facilities  to WYCO, in each case at WIC's
actual total cost. The parties intend that WYCO's  investment in the Front Range
Pipeline and the Powder River Lateral  Expansion  facilities  shall be equal. To
achieve  this  result,  the  percentage  undivided  interest  in  the  Phase  II
facilities to be conveyed to WYCO will be adjusted, if necessary, so that WYCO's
total investment in the Powder River Lateral Expansion facilities (i.e., Phase I
and Phase II  combined)  will be equal to WYCO's  investment  in the Front Range
Pipeline.  In the event that Phase II of the Powder River  Lateral  Expansion is
ultimately  not  constructed  as  planned,   then  WYCO  shall  be  provided  an
opportunity to invest in the next  expansion of the CIG or WIC pipeline  systems
serving the Denver area, and any subsequent expansions, in an amount that causes
the total  investment  of WYCO in the WIC and CIG  expansions to be equal to the
total investment of WYCO in the Front Range Pipeline facilities.

         1.5 The Facilities Leases.  Concurrently with the purchase from PSCo of
the Front Range Pipeline,  PSCo and WYCO will enter into a facilities lease (the
"Front  Range  Pipeline  Lease")  under  which WYCO will  lease the Front  Range
Pipeline facilities back to PSCo. Likewise,  concurrently with the purchase from
WIC of the Phase I facilities  of the Powder River  Lateral  Expansion,  WIC and
WYCO  will also  enter  into a  facilities  lease  (the  "Powder  River  Lateral
Expansion Lease") under which WYCO will lease such interest in the Powder River

                                        5

<PAGE>


Lateral  Expansion back to WIC. A similar lease arrangement will be entered into
between WYCO and WIC  concurrently  with WIC's  transfer to WYCO of an undivided
interest in the Phase II facilities.

         The  initial  term of both of the  Facilities  Leases will be 30 years.
Each  Facilities  Lease will be a "net"  lease  under which PSCo and WIC, as the
case may be, will be solely  responsible  for operations,  maintenance,  repair,
taxes (other than income taxes) and other costs of the leased  facilities.  Upon
expiration of the Facilities  Leases,  the Front Range Pipeline and Powder River
Lateral Expansion facilities will be sold back to PSCo and WIC, respectively, at
the net book  cost.  The Front  Range  Pipeline  Lease is  subject to review and
approval by the CPUC, and the Powder River Lateral Expansion Lease is subject to
review and approval by the Federal Energy Regulatory Commission ("FERC").

                  1.5.1 The Front Range Pipeline  Lease.  Under the terms of the
Front Range Pipeline Lease,  lease payments will be  cost-of-service  based, and
will be calculated annually using rate of return on rate base, depreciation, and
income tax factors authorized by the CPUC.8 In the event that WYCO makes payment
of  property  taxes on the Front  Range  Pipeline,  PSCo would be  obligated  to
reimburse  WYCO for such  amounts.  PSCo shall be obligated to operate the Front
Range Pipeline in accordance  with accepted  industry  standards and shall offer
and provide gas transportation services using such facilities in accordance with
its CPUC gas tariff.  PSCo shall  obtain all  necessary  governmental  approvals
including a certificate  of public  convenience  and necessity from the CPUC for
authorization  to construct and operate the Front Range  Pipeline and to provide
the  additional   transportation   services  created  thereby  with  a  proposed
in-service date of November 1, 1998.

         The Front Range  Pipeline Lease shall be in  substantially  the form of
Exhibit B-1 hereto.

                  1.5.2 The Powder  River  Lateral  Expansion  Lease.  Under the
terms of the Powder  River  Lateral  Expansion  Lease,  lease  payments  will be
cost-of-service  based, and will be calculated  annually using rate of return on
rate base,  depreciation,  and income tax factors authorized by the FERC. In the
event WYCO makes payment of property taxes on the Powder River Lateral Expansion
facilities,  WIC will be obligated to reimburse WYCO for such amounts.  WIC will
be  obligated  to operate the leased  facilities  in  accordance  with  accepted
industry standards and shall offer and provide gas transportation services using
such facilities in accordance with its FERC gas tariff.  WIC, and, to the extent
necessary,  WYCO, shall obtain all necessary  governmental approvals including a
certificate of public  convenience and necessity from the FERC for authorization
to construct and operate the Powder River  Lateral  Expansion and to provide the
additional transportation services created thereby with proposed in-service
- --------
        8   Because the lease payments under the Front Range Pipeline Lease will
be based on and  track the  depreciation  rates,  rate of  return on rate  base,
capital structure and income tax factors used by the CPUC to develop gas service
rates  for  PSCo,   PSCo's  customers  will  be  economically   neutral  to  the
sale/leaseback transaction.

                                        6

<PAGE>


date of November 1, 1998 for Phase I and a proposed  in-service  date of October
1, 1999 for Phase II, market conditions permitting.

         The Powder River Lateral  Expansion Lease shall be in substantially the
same form of Exhibit B-2 hereto.

         1.6  Other  Matters.  WYCO  has no  current  plan to  seek  third-party
financing.  However,  in the  future,  WYCO may seek to finance or  refinance  a
portion of the cost of the  Facilities  through  borrowings  from banks or other
institutional  lenders.  In the event that any such borrowings are made by WYCO,
it is anticipated  that the proceeds thereof would be distributed to Enterprises
and CIGGS as a return of  capital.  Any such debt  securities  would be  secured
solely by the  assets  of WYCO,  including  the  rental  payments  under the two
Facilities  Leases.  The Applicants believe that the issuance of bonds, notes or
other  evidence  of  indebtedness  by WYCO  for the  purpose  of  financing  its
business,  as described in this Application or Declaration,  and the granting of
security therefor,  would be exempt from the requirements of the Act pursuant to
Rule 52(b). WYCO will report any issuance of indebtedness on Form U-6B-2.

         In accordance with its existing  authorization,9  New Century Services,
Inc. ("NC Services"),  a service company subsidiary of NCE, may agree to provide
certain  categories of  administrative,  management,  and technical  services to
WYCO,  in which case NC  Services  and WYCO would  enter into the  standard  NCE
system  service  agreement.  CIG, WIC, or CIGR may also from time to time render
services to WYCO . Prior to providing any such services to WYCO, these companies
would file with the Commission a statement on Form U-13E-1.


Item 2.  Fees, Commissions and Expenses.

         The fees,  commissions  and  expenses  incurred  or to be  incurred  in
connection with the transactions proposed herein are estimated at $15,000.


Item 3.  Applicable Statutory Provisions.

         3.1  Sections  9(a)  and 10 of the  Act are  applicable  to  NCE's  and
Enterprises'  direct or indirect  acquisition of the limited  liability  company
membership  interests  of WYCO  and to  WYCO's  acquisition  of the  Facilities.
Section  12(f) of the Act and Rule 43  thereunder  are deemed  applicable to the
sale of the Front Range  Pipeline by PSCo to WYCO.  Sections  9(a), 10 and 12(f)
and Rule 43 are deemed  applicable  to the lease of the Front Range  Pipeline by
WYCO

<PAGE>


to PSCo and  Sections  9(a) and 10 are  deemed  applicable  to the  lease of the
Powder River Lateral Expansion facilities by WYCO to WIC.

         The  issuance  and sale of debt  securities  by WYCO for the purpose of
financing  its business  are subject to Sections  6(a) and 7 of the Act, but are
considered exempt thereunder pursuant to Section 6(b) and Rule 52(b).

          Future  investments by Enterprises in WYCO in the form of loans,  cash
contributions  or open  account  advances to finance  WYCO's  ongoing  business,
including any expansions of the Facilities, would be subject to Section 9(a) and
10 or Section 12(b) and Rule 45, as applicable,  but will be exempt  pursuant to
Rule 52 or Rule 45(b), as applicable.

                  3.1.1 Standards of Approval under Section 10. The transactions
proposed herein involve an acquisition of securities,  as well as an acquisition
of an interest  in an other  (i.e.,  non-utility)  business,  and are  therefore
subject to the  approval  of this  Commission  under  Section  10. The  relevant
standards for approval  under Section 10 are set forth in  subsections  (b), (c)
and (f). In this case,  the  requirements  of Section 10(f) will be met upon the
approval  of  PSCo's  application  to the  CPUC,  and  there is no basis for the
Commission to make any negative findings under Section 10(b).

         As applied to interests in non-utility businesses,  Section 10(c)(1) of
the Act provides that the Commission  shall not approve an  acquisition  that is
"detrimental  to the  carrying  out of the  provisions  of section  11." Section
11(b)(1),  in turn,  directs the Commission to limit the operations of a holding
company  system to a single  integrated  public-utility  system,  provided that,
subject  to making  certain  specified  findings,  the  Commission  may permit a
registered  holding  company to control  one or more  additional  public-utility
systems.10  Further,  the  Commission  may permit the  retention by a registered
holding company of an interest in any non- utility  business that is "reasonably
incidental,  or economically  necessary or appropriate to the operations" of its
integrated system or systems.  The Commission has interpreted  Sections 10(c)(1)
and 11(b)(1),  read  together,  as  expressing a  Congressional  policy  against
non-utility acquisitions that bear no functional relation to a holding company's
utility operations.11

         As  previously  described,  the Front  Range  Pipeline  is  designed to
transport gas into PSCo's service territory for ultimate  consumption by end-use
customers  served  off of PSCo's gas  distribution  system,  including  fuel for
PSCo's  electric  generation  facilities.  Substantially  all  of  the  capacity
associated  with this facility will be used to support PSCo's retail gas utility
and electric utility operations.  The Powder River Lateral Expansion  facilities
are also designed to

provide PSCo and other customers of WIC with greater access to upstream  sources
of gas supply.  In the past, the Commission has held that investments in similar
kinds of fuel and fuel  transportation  facilities meet the standards of Section
11(b)(1).12

                  3.1.2 Rule 54 Analysis.  The transactions  proposed herein are
also  subject to Section  32(h)(4)  of the Act and Rule 54  thereunder.  Rule 54
provides that, in determining  whether to approve any transaction  that does not
relate to an "exempt wholesale  generator"  ("EWG") or "foreign utility company"
("FUCO"),  the Commission shall not consider the effect of the capitalization or
earnings of any subsidiary  which is an EWG or FUCO upon the registered  holding
company system if paragraphs (a), (b) and (c) of Rule 53 are satisfied.

         Initially,  NCE has  complied or will  comply  with the  record-keeping
requirements of Rule 53(a)(2),  the limitation under Rule 53(a)(3) on the use of
the NCE system's  domestic public- utility company  personnel to render services
to  EWGs  and  FUCOs,  and the  requirements  of Rule  53(a)(4)  concerning  the
submission  of  copies of  certain  filings  under the Act to retail  regulatory
commissions.  Further,  none of the  circumstances  described  in Rule 53(b) has
occurred or is continuing.  Rule 53(c) is  inapplicable by its terms because the
proposals   contained   herein   do  not   involve   the   issue   and  sale  of
securities(including  any  guarantees)  to finance an  acquisition  of an EWG or
FUCO.

         Rule  53(a)(1)  limits a  registered  holding  company's  financing  of
investments in EWGs if such holding company's "aggregate investment" in EWGs and
FUCOs exceeds 50% of its  "consolidated  retained  earnings."  NCE's  "aggregate
investment" (as defined in Rule 53(a)(1)(i)) in all EWGs and FUCOs, pro forma to
include  NCE's   indirect   investment  in  Yorkshire   Electricity   Group  plc
("Yorkshire")13  and Independent  Power  Corporation  plc ("IPC"),  is currently
equal to 50.9% of NCE's  "consolidated  retained  earnings"  (as defined in Rule
53(a)(1)(ii))  for the four  quarters  ended  December 31, 1997.  At the present
time, therefore, NCE does not satisfy all of the requirements of Rule 53(a).

- --------
         12 As indicated,  supra n. 1, in its order  authorizing the creation of
NCE, the  Commission  permitted NCE to retain  interests in certain  non-utility
gas-related  operations  of WGI and e prime.  See also  Central  and South  West
Corporation,  Holding Co. Act Release No. 14555  (December 28, 1961)  (approving
acquisition  of the stock of a gas  pipeline  company by a  registered  electric
utility holding company);  and Conectiv,  Inc., 66 SEC Docket 1260 (February 25,
1998)  (authorizing  new registered  electric  utility holding company to retain
interest in a gas supply and storage  company as being  functionally  related to
holding company's secondary gas distribution system). Further, Commission orders
approving  investments by registered  electric utility holding companies in fuel
and fuel  related  activities  (including  fuel  transportation)  were  cited as
precedents  for  including  such  activities  among  those that  "energy-related
companies," as defined in Rule 58(b), may engage.

         13 In a separate  proceeding (File No.  70-8787),  PSCo is proposing to
transfer to  Enterprises  all of the common stock of New Century  International,
Inc.  ("NCI"),  a  wholly-owned  subsidiary  of PSCo  through  which PSCo holds,
indirectly,  a 50% interest in  Yorkshire.  Upon  completion  of such  transfer,
Enterprises  intends  to file with the  Commission  a  Notification  of  Foreign
Utility Company Status on Form U-57 on behalf of Yorkshire.

         However,  even if the  Commission  were to take into account,  on a pro
forma  basis,  the effect of the  capitalization  and earnings of EWGs and FUCOs
(including,  on a pro forma basis, Yorkshire and IPC) in which NCE has invested,
it would  have no basis  for  denying  the  transactions  proposed  herein.  The
transactions  proposed  herein  relate  solely  to  an  investment,   through  a
non-utility  subsidiary  of  Enterprises,  in  natural  gas  transportation  and
compression  facilities  that will  provide  additional  natural  gas supply and
transportation  capacity  needed by PSCo in  connection  with the conduct of its
domestic natural gas distribution and electric utility  operations.  All aspects
of the  transactions  described  herein,  as  they  relate  to  PSCo  (including
construction  of  the  Front  Range  Pipeline  and  the  related  sale/leaseback
transaction) are subject to the review of and approval by the CPUC.

         Moreover,  there  has been no  material  impact  on NCE's  consolidated
capitalization  by reason of the  inclusion  therein of the  capitalization  and
earnings of EWGs and FUCOs (including on a pro forma basis Yorkshire and IPC) in
which NCE has an interest.  (See Financial Statements F-3 and F-4, showing, on a
pro forma  basis,  the  consolidated  capitalization  and  income  of NCE).  NCE
believes that the capitalization  ratios and income levels are within acceptable
ranges.  Finally,  although  NCE's  consolidated  earnings  for the  year  ended
December 31, 1997, were negatively affected by its investment in Yorkshire, this
was solely as the result of the  imposition by the United Kingdom of a one-time,
non-recurring,  windfall tax on Yorkshire.  Importantly, this tax did not affect
earnings from ongoing operations,  and,  therefore,  would not have any negative
financial impact on earnings in future periods.


Item 4.  Regulatory Approvals.

         The construction of the Front Range Pipeline and the sale and leaseback
thereof by PSCo  pursuant to the Front Range  Pipeline  Lease are subject to the
jurisdiction  of  the  CPUC.14  No  other  state  commission,   and  no  federal
commission,  other  than the  Commission,  has  jurisdiction  over the  proposed
transactions insofar as they concern any of the Applicants.15

         14 On March 9,  1998,  KN  Wattenberg  Transmission  Limited  Liability
Company ("KN  Wattenberg")  filed a complaint  with the FERC against NCE,  PSCo,
Enterprises,  WYCO, CIG, WIC and others alleging,  among other things,  that the
FERC should  assert  jurisdiction  over the Front  Range  Pipeline  project.  KN
Wattenberg  Transmission  Limited Liability Company v. Public Service Company of
Colorado, et al., Docket No. CP98-271. KN Wattenberg, an affiliate of KN Energy,
Inc., has filed an application with the FERC to construct and operate a pipeline
along a similar route and in competition with the Front Range Pipeline. On April
13, 1998, NCE and PSCo, along with other named  respondents,  filed their answer
and motion to dismiss the complaint.

         15 FERC has jurisdiction under the Natural Gas Act of 1938, as amended,
over the construction,  sale and leaseback of the Powder River Lateral Expansion
by WIC, an interstate pipeline company.

                               ARTICLE VII - RENT

      7.1   Rent  Computation.  PSCo,  with WYCO's  approval,  will  compute the
rent  payable by PSCo for the Front Range  Pipeline.  WYCO will  provide  detail
to PSCo as needed to  compute  the  estimated  rent by  December  1 prior to the
calendar  year for which the detail is being  provided.  PSCo will  provide WYCO
with all details necessary to support the rent computation.

            (a)   Estimated  Rent  Computation.  Rent will be  computed  for the
                  appropriate  calendar  year or other period based on best data
                  available to PSCo and WYCO.  If any  components  of the Actual
                  True-Up Rent  Computation , as described  below, are not known
                  or final,  at the time the  computation  is made,  the  latest
                  data  available or in effect will be used for the  computation
                  of the estimated  rent.  The estimated rent  computation  will
                  be  based on the  formula  described  in  Exhibit  B  attached
                  hereto  and   incorporated  by  reference   ("Estimated   Rent
                  Computation").

                                       3
<PAGE>

            (b)   Actual  True-Up  Rent  Computation.  On or before  March 31 of
                  each  calendar  year or ninety  (90) days after the end of any
                  other  rental  period not  ending at  calendar  year end,  the
                  rent  computation  will be recomputed  for the prior  calendar
                  year based on actual  data,  and final  factors  for the prior
                  calendar  year as  available.  WYCO  shall  provide to PSCo by
                  March 1 of each  calendar  year or ninety  (90) days after the
                  end of any  partial  period the data which WYCO has  accounted
                  for which is  necessary to make this  computation.  WYCO shall
                  credit  PSCo's next rent payment for any excess  payments plus
                  interest  at  the  FERC  prescribed   interest  rate  (18  CFR
                  154.501(d))  from the date of each excess  payment  previously
                  made by PSCo  or  refunded  in  cash  if the  Lease  Term  has
                  expired.  PSCo  shall  pay WYCO  any  underpayment  within  15
                  days after  calculating  the Actual True-Up Rent  Computations
                  plus  interest  at the  FERC  prescribed  interest  rate.  The
                  Actual  True-Up  Rent  Computation  will be computed  based on
                  the  formula  described  in  Exhibit  C  attached  hereto  and
                  incorporated    by    reference    ("Actual    True-Up    Rent
                  Computation").  In the event  final  rent  components  are not
                  available  for any  reason,  the  components  used to make the
                  Estimated   Rent   Computation   will  be  used,   with  final
                  adjustments  being  made  within  30 days of final  components
                  being determined.

            (c)   Rent  Components.  The  rent  computation  for  the  Estimated
                  Rent  Computation  and the  Actual  True-Up  Computation  will
                  include the following  components:  (1) depreciation  expense,
                  (2) rate of return on rate base,  and (3)  income tax  factors
                  as  authorized  by the Colorado  Public  Utilities  Commission
                  for recovery by PSCo in its rates.

      7.2 Calculation of Rent for Partial Periods.,
            (a)   For  the  period  commencing  on the  in-service  date  of the
                  Front  Range  Pipeline  through  December  31 of the  calendar
                  year  in  which  the  in-service  date  occurs,  rent  will be
                  computed  based  on the  Estimated  Rent  Computation,  and as
                  revised by the Actual True-Up Rent  Computation,  on an annual
                  basis  and  prorated  based  on the  number  of days  from the
                  in-service date through December 31 of that year.

            (b)   For any other rental period of less than twelve  months,  rent
                  will be  computed  based on the  Estimated  Rent  Computation.
                  and as revised by the Actual  True-Up Rent  Computation  on an
                  annual basis and  prorated  for the number of days  facilities
                  are leased by PSCo.

            (c)   Beginning on January 1st of the calendar  year  following  the
                  in-service  date,  rent will be  computed  on a calendar  year
                  basis based on the Estimated Rent  Computation  and as revised
                  by the Actual True-Up Rent Computation.

      7.3   Payment  Date.  The Rent  payment will be due on or before the tenth
day of the


                                       4
<PAGE>

month  following the calendar  month to which such payment is  applicable.  Rent
shall be  calculated  on a  calendar  year basis but shall be payable to WYCO in
monthly  installments based on the number of months or portions of months in the
calendar year.

      7.4   Regulatory  Changes  Affecting  Rent.  The  calculation  of the Rent
payable  hereunder  shall be based on  rate-making  principles  approved  by the
Colorado  Public  Utilities  Commission in  establishing  PSCo's  jurisdictional
rates.  If during  the term  hereof the  Colorado  Public  Utilities  Commission
adjusts the rate of return,  depreciation,  capital  structure and/or income tax
factors  used in  setting  PSCo's  rates,  adjustment  shall be made in the rent
calculation  in  Section  7.1,  effective  as of the  first  day  of  the  month
following the month in which such adjustments become effective.


                   ARTICLE VIII - WYCO'S PROPERTY OBLIGATION

      WYCO shall preserve and maintain,  throughout the term of this Lease,  all
its  ownership  rights  in  and  to the  Front  Range  Pipeline  to  ensure  the
continued  use by PSCo of the  Front  Range  Pipeline  in the  operation  of its
pipeline system.


                         ARTICLE IX - WYCO'S COVENANTS

      WYCO  hereby  covenants  that if PSCo shall  perform  all the  obligations
required to be  performed  by PSCo under this Lease  Agreement,  PSCo shall have
and  enjoy  the  quiet  and  peaceable  possession  and use of the  Front  Range
Pipeline during the term of this Lease.


                          ARTICLE X - AD VALOREM TAXES

      10.1  Filing Of Returns And  Payment Of Taxes As  Additional  Rent.  PSCo,
on behalf of WYCO,  shall  timely file all Ad Valorem tax returns and render and
pay  (prior  to  delinquency)  all Ad  Valorem  taxes  presently  and  hereafter
enacted which are lawful  obligations of WYCO,  unless  instructed  otherwise by
WYCO and  except  as for the  first  and last  calendar  years of this  Lease as
described  in Section  10.2 below.  Such tax  payments  shall be  considered  as
additional rent.

      10.2  Proration  Of Taxes At  Termination.  PSCo  shall  pay all of the Ad
Valorem  taxes levied on the Front Range  Pipeline  related to the first partial
calendar  year and PSCo shall pay a pro rata share  (based on the number of days
PSCo leased the Front Range  Pipeline  in the  calendar  year) of the Ad Valorem
taxes  levied on the Front  Range  Pipeline  related to the last  calendar  year
prior to the termination of this Lease.

      10.3  Proof Of Payment.  PSCo shall  timely  furnish to WYCO,  receipts of
the  appropriate   taxing   authority  or  other  proof   satisfactory  to  WYCO
evidencing  payment.  PSCo shall  timely  furnish to WYCO a copy of all property
tax assessments, returns and bills for the Front Range Pipeline.



                                       5
<PAGE>

      10.4  Protest  Of Taxes By PSCo.  If PSCo  deems any tax  relating  to the
Front Range  Pipeline  excessive or illegal,  PSCo may defer payment  thereof so
long as the validity or the amount  thereof is contested by PSCo with  diligence
and in good faith.  If at any time  payment of the  contested  tax shall  become
necessary  to prevent  the  delivery  of a tax deed  conveying  the Front  Range
Pipeline  or any  portion  thereof  because  of  nonpayment,  PSCo shall pay the
contested tax in sufficient time to prevent the delivery of any tax deed.

      10.5  Installment  Tax  Payments.  If by law any Ad Valorem tax or special
assessment  with  respect to the Front Range  Pipeline  is  payable,  or, at the
option of the taxpayer,  may be paid in  installments,  PSCo may, whether or not
interest  shall  accrue  on the  unpaid  balance  thereof,  pay the same and any
accrued  interest  or  any  unpaid  balance  thereof  in  installments  as  each
installment  becomes  due  and  payable,  but  in any  event  before  any  fine,
penalty,   interest  or  cost  may  be  added  thereto  for  nonpayment  of  any
installment or interest.

      10.6  Cooperation   Regarding  Tax   Protests.   Any  contest  as  to  the
validity or amount of any Ad Valorem tax or special  assessment  for Front Range
Pipeline  may be made by PSCo in the  name of WYCO or  PSCo,  or  both,  as PSCo
shall  determine,  and WYCO agrees that it will,  at PSCo's  expense,  cooperate
with PSCo in any such  contest to such  extent as PSCo may  reasonably  request.
It is understood,  however,  that WYCO shall not be subject to any liability for
the payment of any costs or expenses in connection  with any proceeding  brought
by PSCo,  and PSCo  covenants to pay and to  indemnify  and save  harmless  WYCO
from any such costs or  expenses.  PSCo shall be  entitled  to any refund of any
Ad Valorem tax or special  assessment  and  penalties or interest  thereon which
have been paid by PSCo to the taxing authority or to WYCO.

      10.7  Deduction  By WYCO.  WYCO shall be able to continue  to deduct,  for
income  tax  purposes,  all real  estate  taxes,  personal  property  taxes  and
special  assessments  on an assessment  date basis.  PSCo agrees to provide WYCO
with such additional  information as WYCO may reasonably  request to assist WYCO
in  maintaining  WYCO's tax  deduction  for these  taxes on an  assessment  date
basis.


                             ARTICLE XI - INSURANCE

      11.1  Required  Insurance  Coverage.  To  protect  WYCO and  PSCo  against

                                ARTICLE VI - RENT

         6.1 Rent Computation.  WIC, with WYCO's approval, will compute the rent
payable by WIC for the Compression  Facilities.  WYCO will provide detail to WIC
as needed to compute the  estimated  rent by December  1st prior to the calendar
year for which the  detail is being  provided.  WIC will  provide  WYCO with all
details necessary to support the rent computation.

                  (a)  Estimated Rent Computation. Rent will be computed for the
                       appropriate calendar year or other period based on best 
                       data available to WIC and WYCO.  If any components of the
                       Actual True-Up Rent Computation, as described below, are
                       not known or final, at the time the computation is made,
                       the latest data available or in effect will be used for
                       the computation of the estimated rent. The estimated rent
                       computation will be based on the formula described in

<PAGE>



                  (b)  Actual True-Up Rent Computation. On or before March 31 of
                       each calendar year or ninety (90) days after the end of 
                       any other rental period not ending at calendar year end,
                       the rent computation will be recomputed for the prior
                       calendar year based on actual data, and final factors for
                       the prior calendar year as available.  WYCO shall provide
                       to WIC by March 1 of each calendar year or ninety (90)
                       days after the end of any partial period the data which
                       WYCO has accounted for which is necessary to make this
                       computation.  WYCO shall credit WIC's next rent payment
                       for any excess payments plus interest at the FERC 
                       prescribed interest rate (18 CFR 154.501(d)) from the
                       date of each excess payment previously made by WIC or
                       refunded in cash if the Lease Term has expired. WIC shall
                       pay WYCO any underpayment plus interest at the FERC
                       prescribed interest rate within 15 days after calculating
                       the Actual True-Up Rent Computations.  The Actual True-Up
                       Rent Computation will be computed based on the formula 
                       described in Exhibit C attached hereto and incorporated
                       by reference ("Actual True-Up Rent Computation").  In the
                       event final rent components are not available for any 
                       reason, the components used to make the Estimated Rent 
                       Computation will be used, with final adjustments being
                       made within 30 days of final components being determined.

                  (c)  Rent   Components.   The  rent  computation  for  the
                       Estimated  Rent  Computation  and the Actual  True-Up
                       Computation  will include the  following  components:
                       (1) depreciation  expense, (2) rate of return on rate
                       base, and (3) income tax factors as authorized by the
                       Federal Energy Regulatory  Commission for recovery by
                       WIC in its rates.

                       the  Compression  Facilities  through  the end of the
                       calendar  year in which the in service  date  occurs,
                       rent will be  computed  based on the  Estimated  Rent
                       Computation,  and as revised  by the  Actual  True-Up
                       Rent  Computation,  on an annual  basis and  prorated
                       based on, the number of days from the in service date
                       until the end of the year.

                  (b)  For any  other  rental  period  of less  than  twelve
                       months,  rent will be computed based on the Estimated
                       Rent Computation.  and as revised by the Actual True-
                       Up Rent  Computation  on an annual basis and prorated
                       for the number of days facilities are leased by WIC.

                       year in which the in service date  occurs,  rent will
                       be  computed  on a calendar  year basis  based on the

         6.3 Payment  Date.  The Rent payment will be due on or before the tenth
day of the  month  following  the  calendar  month  to  which  such  payment  is
applicable.  Rent  shall be  calculated  on a  calendar  year basis but shall be
payable  to WYCO in  monthly  installments  based on the  number  of  months  or
portions of months in the calendar year.

         6.4 Regulatory  Changes  Affecting  Rent.  The  calculation of the Rent
payable  hereunder  shall be based on  rate-making  principles  approved  by the
Federal Energy Regulatory Commission in establishing WIC's jurisdictional rates.
If during  the term  hereof,  FERC  adjusts  the rate of  return,  depreciation,
capital  structure  and/or  income  tax  factors  used in setting  WIC's  rates,
adjustment shall be made in the rent calculation in Section 6.1, effective as of
the first day of the month following the month in which such adjustments  become
effective.


                    ARTICLE VII - WYCO'S PROPERTY OBLIGATION

         WYCO shall  preserve and maintain,  throughout  the term of this Lease,
all its  ownership  rights in and to the  Compression  Facilities  to ensure the
continued  use by WIC of the  Compression  Facilities  in the  operation  of its
pipeline system.


                         ARTICLE VIII - WYCO'S COVENANTS

         WYCO hereby  covenants  that if WIC shall  perform all the  obligations
required to be performed by WIC under this Facilities  Lease, WIC shall have and
enjoy the quiet and peaceable  possession and use of the Compression  Facilities
during the term of this Lease.


                  ARTICLE IX - AD VALOREM TAXES AND OPERATIONS

         9.1 Filing Of Returns And Payment Of Taxes As Additional  Rent. WIC, on
behalf of WYCO,  shall timely file all Ad Valorem tax returns and render and pay
(prior to  delinquency)  all Ad Valorem taxes  presently  and hereafter  enacted
which are lawful  obligations of WYCO, unless  instructed  otherwise by WYCO and
except as for the first and last  calendar  years of this Lease as  described in
Section 9.2 below. Such tax payments shall be considered as additional rent.

         9.2  Proration  Of Taxes At  Termination.  WIC  shall pay all of the Ad
Valorem taxes levied on the Compression  Facilities related to the first partial
calendar  year and WIC shall pay a pro rata  share  (based on the number of days
WIC leased the Compression Facilities in the calendar year) of the last calendar
year prior to the termination of this Lease.

         9.3 Proof Of Payment.  WIC shall timely furnish to WYCO receipts of the
appropriate  taxing  authority or other proof  satisfactory  to WYCO  evidencing

         9.4  Protest  Of Taxes By WIC.  If WIC  deems any tax  relating  to the
Compression  Facilities  excessive or illegal,  WIC may defer payment thereof so
long as the validity or the amount  thereof is  contested by WIC with  diligence
and in good faith.  If at any time  payment of the  contested  tax shall  become
necessary  to prevent  the  delivery  of a tax deed  conveying  the  Compression
Facilities  or any  portion  thereof  because of  nonpayment,  WIC shall pay the
contested tax in sufficient time to prevent the delivery of any tax deed.

         9.5 Installment  Tax Payments.  If by law any Ad Valorem tax or special
assessment  with respect to the  Compression  Facilities is payable,  or, at the
option of the taxpayer,  may be paid in  installments,  WIC may,  whether or not
interest  shall  accrue  on the  unpaid  balance  thereof,  pay the same and any
accrued  interest  or  any  unpaid  balance  thereof  in  installments  as  each
installment becomes due and payable,  but in any event before any fine, penalty,
interest  or cost may be added  thereto for  nonpayment  of any  installment  or
interest.

         9.6 Cooperation Regarding Tax Protests.  Any contest as to the validity
or amount of any Ad Valorem tax or special assessment for Compression Facilities
may be made by WIC in the name of WYCO or WIC, or both, as WIC shall  determine,
and WYCO agrees that it will, at WIC's  expense,  cooperate with WIC in any such
contest to such extent as WIC may reasonably request. It is understood, however,
that WYCO shall not be subject to any  liability for the payment of any costs or
expenses in connection with any proceeding  brought by WIC, and WIC covenants to
pay and to indemnify and save harmless WYCO from any such costs or expenses. WIC
shall be entitled to any refund of any Ad Valorem tax or special  assessment and
penalties  or  interest  thereon  which  have  been  paid  by WIC to the  taxing
authority or to WYCO.

         9.7  Deduction By WYCO.  WYCO shall be able to continue to deduct,  for
income tax purposes,  all real estate taxes, personal property taxes and special
assessments  on an assessment  date basis.  WIC agrees to provide WYCO with such
additional  information  as  WYCO  may  reasonably  request  to  assist  WYCO in
maintaining WYCO's tax deduction for these taxes on an assessment date basis.

Public Service is a wholly-owned subsidiary of New Century Energies, Inc., which
is a registered  public utility holding company under the federal Public Utility
Holding  Company Act. The names and positions of the officers of Public  Service
and its directors are included herein as Exhibit A.

      5.  Existing Gas Service Areas and  Operations.  Public  Service  provides
natural gas sales and transportation  service throughout various portions of the
State of  Colorado,  including  areas in and  along the  Front  Range  from Fort
Collins to Pueblo,  in the Mountain Area from Grand Lake to Vail and  continuing
south to the Durango/Bayfield  area, and in Western Colorado from Grand Junction
north to  Steamboat  Springs and east to Vail.  As related to this  Application,
Public  Service  provides  natural  gas  distribution  service in and around the
greater Denver  metropolitan  area, from communities such as Highlands Ranch and
Parker,  to the  south,  and  communities  such as  Boulder,  Longmont  and Fort
Collins,  to the north.  Public Service also provides  transportation and backup
sales  service to Greeley Gas Company,  a division of Atmos  Energy  Corporation
("Greeley  Gas")  in and  around  portions  of Weld  County,  Colorado.  The gas
supplies  used to serve these and other  communities  are  received  into Public
Service's delivery system (i) primarily from various  interconnections with CIG,
such as the Ault,  Greeley,  Fort Lupton,  East Denver and Whispering Pines town
border   stations,   (ii)  directly  from  Colorado   producing  fields  in  the
Denver-Julesburg  Basin ("DJ Basin") at the  tailgate of several gas  processing
plants located northeast of Denver,  and (iii) from a host of interstate natural
gas pipelines whose  facilities  intersect at and around Public  Service's Chalk
Bluffs compression and measurement facilities ("Chalk Bluffs Station"),  located
just south of the Colorado-Wyoming  state line near Rockport,  Colorado.  Due to

KN Interstate Gas  Transmission  Company  ("KNI") and WestGas  InterState,  Inc.
("WGI").  A map of Public Service's  existing service areas and facilities along
the Front  Range of  Colorado,  and the  location  of the  proposed  Front Range
Pipeline in relation thereto, is attached hereto as Exhibit B.

      6. Certificate of Public Convenience and Necessity and Orders Requested.
      Complete descriptions of the CPCN and the other orders, authorizations and
approvals sought by Public Service herein are as follows:

            (a) Public Service  requests an Order from the Commission  issuing a
CPCN authorizing  Public Service to construct and operate as an integral part of
its local distribution system approximately 53 miles of 24-inch diameter natural
gas pipeline and appurtenant  facilities,  referred to herein as the Front Range
Pipeline.  The Front Range  Pipeline  will extend  from Public  Service's  Chalk
Bluffs  Station  located in Section 5,  Township 12 North,  Range 66 West,  Weld
County,  Colorado,  south to Public Service's existing 24-inch diameter pipeline
located at the Fort St. Vrain valve set in Section 15,  Township 3 North,  Range
76 West,  Weld County  Colorado.  From the Chalk  Bluffs  Station,  the proposed
pipeline will be routed south in the center-to-western half of Range 66 West for
approximately  35 miles  until  the line is just  north  and west of the City of
Greeley.  The  pipeline  will then be  routed  slightly  to the west and  south,
passing  out of  Range  66 West and  into  Range  67 West in the  south  half of
Township  5 North.  The  pipeline  will then be routed  just east of the Town of
Milliken  and west of the Town of  Windsor,  passing to the west of the Fort St.
Vrain Power Plant until the pipeline  terminates  at the existing Fort St. Vrain
valve set. The pipeline will also  interconnect  with Public Service's  existing
Ault,  Fossil Creek and Mead pipelines.  The proposed  construction will include
all necessary metering, controlling, treating and other equipment and facilities
necessary to tie the Front Range Pipeline into Public Service's  existing system
and to safely integrate it into Public Service's gas utility operations.  Public

                                      -5-

Service  anticipates  the  total  cost of  construction  will  be  approximately
$25,107,000.  An estimate of the cost of the Front Range Pipeline is attached as
Exhibit C.
            (b)  Public  Service  also  requests  an Order  from the  Commission
authorizing  the  transfer  of the Front  Range  Pipeline,  upon  completion  of
construction, by sale from Public Service to WYCO Development and the subsequent
immediate  transfer of the Front Range  Pipeline by lease from WYCO  Development
back  to  Public  Service.   Section  40-5-105,   C.R.S.   requires   Commission
authorization  of any transfer of a public utility asset by sale,  assignment or
lease, other than in the ordinary course of business. A copy of the Purchase and
Sale Agreement is attached hereto as Exhibit D and a copy of the Lease Agreement
is attached hereto as Exhibit E.
                  (1) WYCO Development is a Colorado limited  liability  company
which was recently  formed as a part of an alliance  between  Public Service and
CIG to participate  jointly in the prospective  development of pipeline projects
necessary  to provide  additional  capacity  to serve new  market  growth in the
Colorado Front Range.  WYCO  Development is owned 50 percent by NC  Enterprises,
Inc., a wholly-owned  subsidiary of New Century Energies,  Inc. and an affiliate
of Public  Service,  and 50 percent by CIG Gas Supply  Company,  an affiliate of
CIG. The alliance  between Public Service and CIG is discussed more fully in the
direct testimony of Public Service witness Susan Arigoni, attached hereto. Under
the terms of the alliance,  and provided that all necessary regulatory approvals
of the sale and leaseback  transactions are obtained from this  Commission,  the
Federal Energy Regulatory Commission and the Securities and Exchange Commission,
Public  Service's  affiliate  and CIG's  affiliate  will  each own a 50  percent
membership  interest in WYCO Development,  which will be the title holder of the
investment in the Front Range Pipeline and other proposed pipeline projects.
                  (2) The  purchase  price  to be paid  by WYCO  Development  to
Public  Service for the Front Range  Pipeline  will be based on the actual total
cost  incurred  by Public

                                      -6-

<PAGE>

Service to construct  the Front Range  Pipeline,  as accounted for in accordance
with the Gas Plant  Instructions  of the Uniform  System of Accounts,  18 C.F.R.
Part 201,  plus an allowance for funds used during  construction.  In connection
therewith,  Public Service requests that the Commission's Order provide that the
investment  made by Public  Service in the Front Range Pipeline be accounted for
and  maintained in the Company's  construction  work in progress  account,  such
construction work in progress to have capitalized cost of money added to it on a
monthly basis in an amount equal to Public  Service's  then  authorized  rate of
return on rate  base  during  the  period  of time  when the  pipeline  is under
construction and prior to the time that the pipeline is placed into service.
                  (3) The initial term of the lease is 30 years.  After the term
expires, the Front Range Pipeline will be sold to Public Service at its net book
value.  Under  the  lease,  Public  Service  will have the same  possessory  and
operational  rights  and duties  that it would have if it owned the Front  Range
Pipeline outright.  Public Service will be responsible for all of the operation,
maintenance and repair of the facilities.  The lease payments will be based upon
and will track the  depreciation  rates,  rate of return on rate  base,  capital
structure,   and  income  tax   factors   used  to  develop   Public   Service's
Commission-authorized  gas  service  rates and will be  structured  so as not to
exceed the cost of service  effect that Public  Service  would have realized had
the  Front  Range  Pipeline  always  been  included  in  rate  base.  Thus,  the
sale/leaseback  arrangement is designed to have  absolutely no adverse  customer
impacts.  In fact,  Public Service's  customers will be economically  neutral to
this arrangement.
            (c)  In  addition  to  approval  of  the   proposed   sale/leaseback
transactions,  Public Service requests that the Commission  declare in its Order
that  WYCO  Development will not be a public utility under sections 40-1-103(1),
C.R.S., by virtue of its ownership  interest in the Front Range Pipeline.  Under
the proposed agreements and transactions covering the Front Range Pipeline, WYCO
Development is merely a holder of an investment in a public  utility asset,  and
is akin to a financial  institution  or other mortgage  holder.  Inasmuch as the

                                      -7-

<PAGE>

construction,  operation,  custody and control of the Front Range  Pipeline will
remain in Public Service, a natural gas public utility over which the Commission
has full and continuing regulatory jurisdiction, there is no basis upon which to
assert  jurisdiction  over WYCO  Development.  Public Service will construct the
Front Range Pipeline and own it during construction. Public Service will operate
and  maintain  the  pipeline  along  with its other  local  distribution  system
facilities  over which the  Commission  has  jurisdiction.  And finally,  Public
Service  will  provide  Commission-jurisdictional  gas sales and  transportation
services  utilizing  the Front Range  Pipeline  pursuant to its Colorado PUC No.
6-Gas Tariff.
                  (1) The Commission has previously disclaimed jurisdiction over
entities holding title to public utility facilities in similar circumstances. In
Decision No. C95-520,  the Commission issued its "Decision Granting Petition for
Declaratory Relief," wherein it declared that Walden Capital Leasing Corporation
("WCLC"),  a non-profit  corporation  which was created by the Town of Walden, a
statutory  municipality,  to finance the  construction of a natural gas pipeline
and the  transfer of certain gas  distribution  facilities  from Rocky  Mountain
Natural Gas Division of KN Energy, Inc. was not a public utility. In disclaiming
jurisdiction over WCLC, the Commission found as follows:

            Although WCLC will hold contract and legal title to the distribution
            system and interconnecting pipeline, the petition points out that it
            will do so only as a financing agent for Walden.  Walden itself will
            operate and maintain the public utility facilities,  and will be the
            entity providing service to the public.
                  . . . We agree  with the  petition  that WCLC as
            the  "passive  investor"  holding  bare legal title to
            the subject  assets should not be found to be a public
            utility subject to our authority.1
Like WCLC, WYCO Development will merely be a "passive  investor,"  "holding bare
legal title" to the Front Range Pipeline.  Unlike that case, however,  where the
operating utility was

<PAGE>

a municipality  exempt from the Commission's  jurisdiction,  the Commission here
will  retain  the full  extent of its  jurisdiction  over the  operating  public
utility even if it disclaims jurisdiction over the nominal title holder.
                  (2) In a similar case in Decision No. C91-1729, the Commission
approved the transfer of numerous  electric  generating and transmission  assets
formerly owned by Colorado-Ute Electric  Association,  Inc., through its trustee
in  bankruptcy,  to  Public  Service,   Tri-State  Generation  and  Transmission
Association,  Inc.  ("Tri-State"),  and  Pacificorp  Electric  Operations,  Inc.
("Pacificorp").  While the Commission  already had regulatory  jurisdiction over
Public Service and Tri-State before the transfer, it did not previously regulate
Pacificorp.  The  Commission  found that simple  ownership in the public utility
assets,  without more, did not invoke  Commission  jurisdiction over Pacificorp:
"Pacificorp  does not propose to serve any customers in the state of Colorado by
generating,  transmitting  or  distributing  electricity  to  them.  Under  such
circumstances, Pacificorp is not a public utility within the  meaning of section
40-1-103(2)(a),  C.R.S. (1984 Repl. Vol.)."2 Accordingly,  the Commission should
disclaim  jurisdiction over WYCO Development in its Order approving the proposed
sale/leaseback transactions.
            (d) Public Service seeks  authority to commence  construction by May
23, 1998, so that it may complete  construction  of the Front Range Pipeline and
place it into  service by November  1, 1998,  in time for the  1998-1999  winter
heating  season.  The pipeline needs to be completed and in service on or before
November  1, 1998 so that  sales  customers  of Public  Service,  as well as its
transportation customers, may make gas supply arrangements for the winter season
which  realize the numerous  benefits  from the  additional  system  flexibility
created by the Front Range Pipeline.  The Company  anticipates that construction
of the Front Range Pipeline will require  approximately  five to six months from
the date of Commission  authorization.  A Commission Order issued any later than
May 22, 1998 will

<PAGE>

provide a  significant  degree of  uncertainty  for both Public  Service and its
transportation  customers when entering into supply and transportation contracts
with  producers and upstream  transportation  providers to meet their  1998-1999
winter energy needs. Consequently, Public Service respectfully requests that the
Commission issue an Order granting the  above-requested  approvals no later than
May 22, 1998.
            (e) In  addition,  Public  Service  asks for such other and  further
Orders as may be necessary or  desirable  in order to permit  Public  Service to
construct the Front Range Pipeline and place it in service by November 1, 1998.
      7. Type of Utility Service to be Rendered. Public Service, upon receipt of
a Commission Order approving the requests  herein,  will operate the pipeline as
part of its integrated  local  distribution  system,  and as such,  will use the
pipeline to receive gas into its  distribution  system from  various  interstate
pipelines for system supply and on behalf of its  transportation  customers.  In
addition,   Public  Service  anticipates  using  the  Front  Range  Pipeline  to
transport,  through backhaul or displacement,  gas which is received from the DJ
Basin and other  points for  delivery  into  interstate  pipelines  at the Chalk
Bluffs Station and destined to off-system  markets.  Such transportation will be
performed pursuant to a  limited-jurisdiction  certificate issued by the FERC in
Docket No. CP92-633,3  authorizing  Public Service,  as a Hinshaw  pipeline,  to
engage in transportation in interstate  commerce in the same way and to the same
extent as intrastate  pipelines pursuant to secton 311(a) of the Natural Gas 
Policy Act of 1978.
      8.  Financial  Statements.  In  accordance  with Rule 55(c) (5),  attached
hereto as Exhibit F are the Balance Sheet,  Income  Statement,  and Statement of
Retained  earnings of Public  Service  Company of Colorado as of  September  30,
1997.
      9. Proposed  Tariff or Rates.  Public  Service is not  requesting any rate
adjustments  or  proposing  any special  rate or tariff for this project at this
time.  The  Company

will include the annual lease costs of the Front Range Pipeline with its overall
natural gas distribution system costs that are allocated to all customers in its
next gas rate case. As Public Service has done with similar  facilities and CPCN
requests,  Public  Service is deferring  other cost  allocation  and rate design
issues to the Company's next general rate proceeding before the Commission.  The
estimated  impact of inclusion of the Front Range Pipeline lease costs on Public
Service's customers is detailed in the attached Exhibit G.
      10. Other Public Utilities. Applicant is aware that other public utilities
are currently  operating near the proposed pipeline;  however,  Applicant is not
aware of other state-regulated  utilities that will be providing similar service
as that  proposed by  Applicant,  i.e.,  high pressure  pipeline  service,  with
interconnections to and from various interstate  pipelines and  interconnections
with Public Service's  current  distribution  system.  Applicant is aware of the
pipeline proposal of KN Wattenberg  Transmission  Limited Liability Company ("KN
Wattenberg"),  currently pending before the Federal Energy Regulatory Commission
("FERC")  in Docket  No.  CP98-49,  in which this  Commission  has filed its own
motion to intervene.
      11. Public Convenience and Necessity Requirements.  The public convenience
and necessity require the construction and operation of the proposed Front Range
Pipeline by Public Service for the following reasons:
            (a) As explained in detail in the direct testimony of Public Service
witness  Haeger,  the  Front  Range  Pipeline  is the  natural  final leg of the
numerous gas system  projects  undertaken by Public  Service under its long-term
facility plan and will provide  much-needed  delivery capacity and supply access
to the Colorado Front Range market commencing in the 1998-1999 winter season and
well into the next century.  The Front Range  Pipeline  will provide  additional
supply  access  and   operational   benefits  to  Public   Service's  sales  and
transportation  customers,  while relieving a transportation  bottleneck between
major  interstate 

                                      -11-

<PAGE>

pipelines at the Chalk Bluffs Hub and Public Service's distribution territory in
the Denver metropolitan area.
            (b) As previously presented in evidence offered by Public Service in
support of its request in Docket No.  95A-169G  for a CPCN for the 24-inch  Fort
St. Vrain  Pipeline,  "Phase I" of the Front Range Pipeline  project,  the Front
Range Pipeline is necessary to provide supply transportation alternatives and to
access additional gas supply sources.  The total overall pipeline project was to
encompass a 24-inch pipeline  originating from the Chalk Bluffs Station,  to the
north, and terminating at an interconnection with Public Service's  distribution
system,  to the south, at the Tri-Town valve set located between Fort Lupton and
Frederick. The first phase of the project, the Fort St. Vrain Pipeline extending
from the Tri-Town valve set to the Fort St. Vrain valve set, was approved by the
Commission in Decision No.  C95-636.  In granting the CPCN to Public  Service in
that  proceeding,  the  Commission  addressed  the second  phase of the project,
finding that "the future extension of the pipeline north to the Chalk Bluffs Hub
will allow the Company to directly access several  interstate  pipelines and the
gas  supply  sources  connected  to those  pipelines  to serve its  natural  gas
customers along the Front Range." Referencing the overall pipeline project,  the
Commission  further found that "the pipeline will allow Public Service to access
natural gas supplies from new sources.  This increased diversity of gas supplies
will likely benefit both electric and gas customers."
            (c) The  population  and  economy  of the Front  Range of  Colorado,
including  the various  cities and towns  therein,  are growing at a rapid pace.
Consequently,  the peak day  demand  and annual  consumption  of natural  gas on
Public Service's  system has been increasing at a steady rate.  Market forecasts
indicate  that the growth along the Front Range will  continue to increase  into
the foreseeable future.
            (d) The  present  distribution  facilities  of  Public  Service  are
limited in their  ability to serve  Public  Service's  growing  market along the
Front  Range  and in their  ability  to

                                      -12-

<PAGE>

receive natural gas from interstate  pipelines other than CIG. The  construction
of the Front Range  Pipeline will enable  Public  Service to expand its delivery
capacity and provide  additional supply access to the Chalk Bluffs Hub, which is
a major confluence of several interstate pipelines near Rockport, Colorado. This
will  provide  both  Public  Service  and its  customers  access to these  other
pipelines and,  therefore,  to natural gas supplies in many production areas and
supply basins in the Rocky Mountain Region.  This improved access should lead to
lower priced supplies  becoming  available to the Front Range market.  The Front
Range  Pipeline will be desirable and  beneficial to Public  Service's  existing
customers in the near future,  when Public Service and other Colorado  utilities
commence  implementation  of their plan to unbundle  natural gas rates and allow
residential and commercial customers the opportunity to choose among natural gas
suppliers.  The Front Range Pipeline will provide  enhanced access  advantage to
Public   Service's   customers  in  the  evolving   unbundled  and   deregulated
environment.
            (e) There are a considerable number of interstate pipelines standing
ready to provide  access to  upstream  gas  supplies  to Public  Service and its
customers at the Chalk Bluffs Hub. As stated  above,  CIG, WIC,  Williams,  KNI,
Trailblazer   and   WGI   are   interstate   pipelines   that   currently   have
interconnections  at Chalk Bluffs.  Public Service's ability to receive gas from
these  pipelines  is currently  provided by a single  8-inch  pipeline  that has
capacity to transport  very limited  quantities  of natural gas. The addition of
the 24-inch Front Range Pipeline will further  develop Chalk Bluffs into a major
"market  area"  where  buyers and  sellers  of  natural  gas meet and enter into
transactions,  which should provide benefits to all Public Service customers. In
addition,  Public  Service's  existing  transportation  customers have expressed
interest and/or made requests for the change of their existing receipt points on
Public Service's distribution system to Chalk Bluffs. As discussed above, Public
Service currently does not have available capacity to provide for such requested
changes in receipt points.

                                      -13-

<PAGE>

            (f) The peak day  capacity of the proposed  Front Range  Pipeline is
approximately  269,000  Dth per day.  Because  of the rapid  growth in the Front
Range,  Applicant  anticipates that this initial capacity will be fully utilized
by  shifting  gas  supply  purchases  of  75,000  Dth per day to  Chalk  Bluffs,
increased  annual  system peak day growth of 200,000 Dth per day in the next few
years  and  finally  by  transportation  customers  requesting  shifts  in their
transportation  receipt points to Chalk Bluffs. This utilization is described in
more detail in Witness Haeger's testimony.
            (g) Public Service has considered alternatives to the proposed Front
Range Pipeline to determine if equivalent  capacity could be obtained in another
form. Based on this review,  Public Service has determined that optimal benefits
are  provided by building the Front Range  Pipeline  project and  extending  the
Public  Service  city-gate  to the Chalk  Bluffs Hub.  One  current  alternative
reviewed was potential  utilization of the proposed KN Wattenberg  "Front Runner
Pipeline."  Utilization of this alternative would provide additional capacity to
the Front Range Market, but would not provide commensurate  benefits provided by
Public Service's Front Range Pipeline project. Disadvantages of the Front Runner
Pipeline option include higher costs based on its higher investment  requirement
for virtually the same capacity,  KN Wattenberg's existing rates, the problem of
rate  stacking,  restrictions  on  movement  of the  city  gate,  and  increased
administrative  burden  in  nomination  and  scheduling  by the  addition  of an
intervening third party pipeline.
            (h) The  repowering  of Fort St.  Vrain  has been  determined  to be
necessary  for Public  Service  to meet the  forecasted  demand of its  electric
customers. The second phase of the Front Range Pipeline project will continue to
enhance  supply  options  for Fort St.  Vrain to source  both fuel and  capacity
needed to generate electricity required by Public Service's electric customers.
            (i) The  completion of the second phase of the Front Range  Pipeline
project  will offer  Public  Service  additional  options for the  provision  of
natural  gas sales and

                                      -14-

<PAGE>

transportation  service to the Front  Range  Market.  The Front  Range  Pipeline
reinforces Public Service's delivery system that serves Fort St. Vrain and other
Public  Service  customers.  The  diversity of gas supplies that can be accessed
will increase the  reliability  of Public  Service's  distribution  system while
allowing  more  competitive  gas  supply  choices  for  Public  Service  and its
customers.
            (j) The Front Range  Pipeline  project via an alliance with CIG will
prevent  duplicative  facilities  and result in a facility that can meet current
and future needs. Public Service plans to use a combination of existing electric
transmission  and pipeline  rights-of-way  in routing the pipeline between Chalk
Bluffs  and  Fort St.  Vrain.  To  minimize  customer  impacts  and  costs,  the
construction of one pipeline sufficient to serve the needs of Public Service and
its market is in the public  interest  from both an economic  and  environmental
standpoint.
      12.  Environmental  Concerns and Compliance.  Necessary  permits have been
applied for and the required  studies are either  complete or are in the process
of being  completed.  The pipeline  route has been  selected  with a view toward
minimizing  environmental  impacts.  As indicated above, Public Service plans to
use a combination of existing electric  transmission and pipeline  rights-of-way
in routing the pipeline  between Chalk Bluffs and Fort St.  Vrain.  In addition,
the construction  schedule is being planned so as to prevent  interference  with
critical  wildlife  activities.  The  project  is  being  designed  and  will be
constructed   and   operated  so  as  to  prevent   any  adverse   environmental
consequences.  In  addition,  natural gas supply  provided by this  project is a
clean burning energy source with adequate regional supply availability that will
promote both a cleaner environment and energy independence.
      13.  Qualifications  of Public  Service.  Public  Service has provided gas
service  in the State of  Colorado  for over 120 years  and is the  largest  gas
utility in the state.  Public Service  employs  highly  skilled and  experienced
personnel to manage the  construction and

                                      -15-
<PAGE>

operations  of its  natural  gas  pipeline  systems.  Public  Service  is  able,
financially  and  operationally,  to  construct  and  operate  the  Front  Range
Pipeline.
      14.  Related  Agreements.  The  following  agreements  will be executed by
Public Service and WYCO  Development  upon the completion of the construction of
the pipeline and the receipt of all necessary regulatory approvals:
            (a) Front Range Pipeline Purchase and Sale Agreement. This agreement
will be entered into by and between  Public  Service and WYCO  Development  upon
completion of construction of the Front Range Pipeline by Public Service and the
receipt of all necessary  regulatory  approvals.  The agreement provides for the
terms of the sale of the  Front  Range  Pipeline  from  Public  Service  to WYCO
Development. This agreement is attached hereto as Exhibit D.
            (b) Lease Agreement.  This agreement,  attached hereto as Exhibit E,
will be entered into by and between Public  Service and WYCO  Development at the
same time the purchase  and sale  agreement is executed and will provide for the
terms of the 30-year  lease of Front Range  Pipeline  from WYCO  development  to
Public  Service.  The lease also sets forth the duties and  obligations  of each
party with  respective to the operation and  maintenance,  accounting  and lease
payments.
      15.  Place of Hearing.  In the event a hearing is deemed  necessary by the
Commission,  Public Service  requests that it be held in one of the Commission's
hearing rooms in Denver, Colorado. If there are no protests or interventions, or
if such protests or interventions are insubstantial, Public Service requests the
Commission decide this matter without a hearing.
      16. Public Service  understands  that the mere filing of this  Application
does not, by itself, constitute authority to operate, and that any sums expended
by Public  Service prior to Commission  authorization  are at the risk of Public
Service.

                                      -16-

<PAGE>

      17. Upon the issuance of the authority  sought  herein,  Applicant  states
that it will operate the pipeline in accordance  with all applicable  Commission
Rules and Regulations.
      WHEREFORE,  Public Service Company of Colorado  respectfully requests that
the  Commission: (i) set this matter for expedited procedure pursuant to section
40-6-109(5), C.R.S. and, if the matter is to be heard, to hear the matter itself
and  issue an order  thereon  by May 22,  1998;  (ii)  grant  Public  Service  a
certificate of public  convenience and necessity  authorizing  Public service to
construct  and operate the Front Range  Pipeline;  (iii) approve the transfer of
the Front Range Pipeline by sale from Public Service to WYCO Development and the
transfer back to Public Service by lease from WYCO  Development;  (iv) enter its
order  providing for the requested  treatment of investment in the  construction
work in  progress  account,  including  capitalized  cost of money;  (v) issue a
declaratory  ruling that WYCO Development will not be a public utility by virtue
of its nominal  ownership  interest in the Front Range Pipeline;  and (vi) enter
its  further  or  different  orders or  authorizations  as may be  necessary  or

              Exhibit H - Proposed Form of Federal Register Notice


New Century Energies, Inc., et al.  (70-[____])

         New Century Energies,  Inc. ("NCE"), 1225 17th Street, Denver, Colorado
80202-5533,  a registered  holding  company,  its electric  utility  subsidiary,
Public Service Company of Colorado ("PSCo"),  1225 17th Street, Denver, Colorado
80202-5533,    and   its   non-utility   subsidiary,   NC   Enterprises,    Inc.
("Enterprises"),  1225 17th Street, Denver,  Colorado 80202-5533  (collectively,
the "Applicants"), have filed an application or declaration under sections 9(a),
10, 12(b) and 12(f) of the Act and rules 43, 45, and 54 under the Act.

         The Applicants  request approval for various  transactions  relating to
the sale and  leaseback by PSCo of a newly  constructed  approximately  53-mile,
24-inch diameter, natural gas pipeline that is designed to transport natural gas
from a point of interconnection with PSCo's existing measurement and compression
facilities  located  just south of the  Colorado-Wyoming  border near  Rockport,
Colorado,  to an interconnection  with PSCo's existing 24-inch diameter pipeline
near PSCo's Ft.  Vrain  generating  station (the "Front  Range  Pipeline").  The
estimated  cost of  construction  of the Front Range  Pipeline is $25.1 million.
PSCo is seeking a  certificate  of public  convenience  and  necessity  from the
Colorado  Public  Utilities  Commission  ("CPUC") to  construct  the Front Range
Pipeline.  Subject to  receipt  of the CPUC  order,  PSCo  intends  to  commence
construction  of the new pipeline  with a view to  completing  construction  and
placing  the  facility  in service by  November  1, 1998 in time for the 1998-99
winter heating season.

         In addition to PSCo's construction of the Front Range Pipeline, Wyoming
Interstate  Company ("WIC"),  an interstate  natural gas pipeline and certain of
its affiliated companies, have agreed to construct certain facilities, including
new  compression  facilities  and  later,  market  conditions   permitting,   an
approximately 100-mile,  16-inch diameter,  pipeline (collectively,  the "Powder
River Lateral Expansion") which will provide additional  transportation capacity
from Wyoming producing basins into the Rockport,  Colorado area. The Front Range
Pipeline  and  Powder   River   Lateral   Expansion   together   will   increase
transportation  capacity  into PSCo's  natural gas service area and will provide
PSCo and its transportation customers with improved access to upstream suppliers
of  natural  gas in  production  areas and supply  basins in the Rocky  Mountain
Region.

         In order to coordinate and jointly manage the  development of the Front
Range Pipeline and Powder River Lateral Expansion projects,  it is proposed that
Enterprises  and CIG Gas Supply  Company  ("CIGGS"),  an affiliate of WIC,  will
organize and acquire the membership interest of WYCO Development LLC ("WYCO"), a
special  purpose   non-utility   limited  liability  company  to  be  formed  by
Enterprises  and CIG.  Enterprises  and CIG will each own 50% of the  membership
interests  of WYCO.  WYCO  proposes to purchase the Front Range  Pipeline,  upon
completion,  from PSCo and the Powder River Lateral Expansion,  upon completion,
from WIC and  simultaneously  enter into 30-year lease  agreements with PSCo and
WIC pursuant to which

the completed facilities would be leased back to PSCo and WIC, respectively. The
facilities  would be  purchased  by WYCO for an amount  equal to the total  cost
incurred by PSCo and WIC, plus an allowance for funds used during construction.

         Lease payments under the facility leases will be cost-of-service based,
and will be calculated  annually using rates of return,  depreciation and income
tax  factors  authorized  by the CPUC (in the  case of the PSCo  lease)  and the
Federal Energy Regulatory  Commission (in the case of the WIC lease). Each lease
will be a net lease under which PSCo and WIC, as the case may be, will be solely
responsible for operations,  maintenance,  repair,  taxes and other costs of the
leased facilities.

         Initially,  all of the funds required by WYCO to purchase the completed
facilities will be supplied by Enterprises and CIG, respectively. In the future,
it is contemplated  that WYCO may seek to refinance a portion of the cost of the
facilities  with the proceeds of  borrowings.  WYCO would report the issuance of
any such debt securities (and any guaranty  thereof by Enterprises)  pursuant to
rule 52(b) under the Act on Form U-6B-2.
